Good news!
If we can realize nuclear fusion as a reliable energy source on earth then the Global Warming hoax and Climate Change religion would immediately collapse and be exposed as one of the greatest scams ever known to humans!
"Researchers led by Chang Liu of PPPL [Princeton Plasma Physics Laboratory] have unveiled a promising approach to mitigating damaging runaway electrons created by disruptions in Tokamak fusion devices. Key to the approach was harnessing a unique type of plasma wave that bears the name of astrophysicist Hannes Alfvén, a 1970 Nobel laureate.
Alfvén waves have long been known to loosen the confinement of high-energy particles in tokamak reactors, allowing some to escape and reducing the efficiency of the doughnut-shaped devices. ...
Researchers derived a theory for the remarkable circularity of these interactions. The results aligned well with runaways in experiments on the DIII-D National Fusion Facility, a DOE tokamak that General Atomics operates for the Office of Science. Tests of the theory also proved positive on the Summit supercomputer at Oak Ridge National Laboratory. ...
Disruptions start with sharp drops in the million-degree temperatures required for fusion reactions. These drops, called “thermal quenches,” release avalanches of runaways similar to earthquake-produced landslides. “Controlling disruptions stands as a paramount challenge to the success of tokamaks,” ..."
From the abstract:
"Alfvénic modes in the current quench (CQ) stage of the tokamak disruption have been observed in experiments. In DIII-D the excitation of these modes is associated with the presence of high-energy runaway electrons (REs), and a strong mode excitation is often associated with the failure of RE plateau formation. In this work we present results of self-consistent kinetic-MHD simulations of RE-driven compressional Alfvén eigenmodes (CAEs) in DIII-D disruption scenarios, providing an explanation of the CQ modes. Simulation results reveal that high energy trapped REs can have resonance with the Alfvén mode through their toroidal precession motion, and the resonance frequency is proportional to the energy of REs. The mode frequencies and their relationship with the RE energy are consistent with experimental observations. The perturbed magnetic fields from the modes can lead to spatial diffusion of REs including the nonresonant passing ones, thus providing the theoretical basis for a potential approach for RE mitigation."
